Dumb question that I wouldn't ask except it happened to me on our first trip out. When the slides and jacks wouldn't deploy, was the engine running? Long story, but I didn't realize there was an interlock that kept the slides from working (and the awning) if the engine is running. Repair guy explained that some RV's interlock to the parking brake, others to the ignition. I just happen to have one that interlocks to the engine. Felt like an idiot but at least I know better next time.
